The Science Behind Creativity

APA Monitor on Psychology article by Kirra Weir (2022), surveying where creativity research stands after a generation of neuroimaging. The article pulls together John Kounios, Adam Green, Jonathan Schooler, Anna Abraham, Paul Seli, and Mark Runco — a cross-section of the researchers actively disagreeing about how to define and measure the thing they study.

What Is Creativity?

The standard definition — novel and useful — is contested by almost everyone who uses it. "Useful to whom?" is unresolved. A theorem with no application for a century, then foundational to string theory, complicates the picture. Runco's proposed addition is authenticity: genuine creative expression rather than recombination for its own sake.

Kounios prefers a different frame altogether: creativity as the ability to take elements of thought, break them down, and reorganize them into something new. A poem rearranges words. A melody rearranges notes. A theorem rearranges the grammar of mathematics. This definition sidesteps the utility problem and keeps creativity open across domains.

How It Gets Measured (and Where That Fails)

The standard lab measure is divergent thinking, going back to psychologist J.P. Guilford's 1950 APA presidential address. The most common test: how many uses can you find for a brick? But divergent thinking scores don't correlate well with real-world creative achievement. Being fluent at brick repurposing doesn't predict musical composition or scientific discovery. The measurement problem remains open.

One way out is to stop measuring creative products and start watching creative processes in the brain. Neuroimaging allows researchers to observe what is actually happening as a creative thought forms.

Creativity in the Brain

What the brain imaging shows is that creativity involves a cooperation between two networks that are normally antagonistic. The cognitive control network handles executive functions — planning, problem-solving, focused attention. The default mode network activates during mind-wandering and daydreaming. These two systems usually suppress each other. Creative thinking seems to be one of the rare states where they work together.

Adam Green's lab has also found that the frontopolar cortex — in the brain's frontal lobes — is specifically associated with creative thinking. Stimulating it with transcranial direct current stimulation caused participants to generate analogies that were more semantically distant, that is, more creative. This doesn't make the frontopolar cortex the creative region — Kounios is direct about this: "Creativity is not one system but many different mechanisms that, under ideal circumstances, work together in a seamless way."

The Eureka Moment

Kounios distinguishes two routes to a creative solution. System 1 (fast, unconscious): the aha moment, where the answer bursts into awareness. System 2 (slow, deliberate): working through the problem consciously. Both can produce creative results; they often work in sequence, with System 1 generating ideas and System 2 refining them.

A relevant warning from Schooler: the rush of a eureka moment inflates the perceived importance of an idea. In his study of creative writers and physicists, ideas that arrived during mind-wandering were initially rated as highly important — but six months later, revisited, participants rated them as creative but less important than they had thought. The aha experience may be a visceral marker but it can also misfire. Don't be afraid to return and critique an insight.

Paul Seli's hypnagogia experiments add another dimension. The state between waking and sleep — where remote ideas connect more freely — produced paintings rated significantly more creative than those from ordinary waking thought. "In dream states, we seem to be able to link things together that we normally wouldn't connect," he said.

Personality and Practice

Openness to experience is the strongest personality predictor of creativity across age groups — it draws people toward new experiences and new ways of engaging with the world. But creativity is also a state, not only a trait. Anyone can push toward it.

The practical conditions that help: mind-wandering with purpose, spending time in nature and wide-open spaces (perceptual attention and conceptual attention are linked — an expanded environment expands the scope of thought), working during off-peak hours when thinking is fuzzier and less analytical, and — most reliably — simply practicing. "Creativity isn't something that comes magically. It's a skill, and as with any new skill, the more you practice, the better you get."

Main Lesson

The research converges on an uncomfortable point: the things that help creativity (relaxation, wide spaces, mind-wandering, off-peak hours) are structurally at odds with how most productive environments are organized (deadlines, cubicles, coffee, analytical focus). Understanding the difference between the conditions that generate ideas and the conditions that refine them is the practical takeaway.
